Tennis-Federer demolishes Zverev to reach Halle last four

BERLIN, June 14

BERLIN, June 14 World number three Roger Federer needed a mere 39 minutes to demolish hapless wild-card entrant Mischa Zverev of Germany 6-0 6-0 and book his spot in the Gerry Weber Open semi-finals on Friday.

The Swiss was in spectacular form on Halle's grass courts, gifting the world number 156 not a single break ball throughout the match which was only his second double-bagel win in his career, according to tournament organisers.
